Where to put .fadein() in ajax pagination - php

I done ajax pagination (by watching tutorial) but now i need to add fadein effect and i cant figure how. I tried to add .fadeIn() probably everywhere but it wont work and i dont know where to put it. What i want to do is smooth page change.
Here is my script i think i dont need to add php.
And i have only back and next options. Not numbers of sites.
<script>
$(document).ready(function(){
//showing the data without refresh but on going to next pagination
setTimeout(function(){
load_fn_data();
}, 1000);
function load_fn_data(page){
$.ajax({
url:"data.php",
method:"POST",
data: {
page:page
},
success: function(data){
$('#load_data').html(data);
}
});
}
$(document).on('click','.pagination_link',function(){
var page = $(this).attr("id");
load_fn_data(page);
});
});
</script>

Hide before, than .html and afterwards .fadeIn() on success like:
function load_fn_data(page){
$('#load_data').hide()
$.ajax({
url:"data.php",
method:"POST",
data: {
page:page
},
success: function(data){
$('#load_data').html(data).fadeIn(800);
}
});
}

jQuery ajax request awkward issue

So I have this ajax request. When the user clicks an edit link, I fetch the ID of the entry and refresh the page with the data of that entry loaded into a form.
Here's my problem: This only works with the alert showing before the ajax call. When I leave out the alert, I get an ajax error (though the id is being posted) and the PHP page just reloads. Moreover, it only works when I put the newDoc stuff as a success callback. The exact same lines as a complete callback and the page reloads. Moreover, this occurs in Firefox only.
jQuery('a.edit').on('mousedown', function (e) {
e.preventDefault();
var id = jQuery(this).attr('data-title');
alert('test');
jQuery.ajax({
url: document.location,
data: {
id: id
},
success: function (data) {
var newDoc = document.open("text/html", "replace");
newDoc.write(data);
newDoc.close();
},
error: function () {
alert('error');
}
});
});
What can I do?
EDIT: This must be a timing issue. I just noticed that when I click and hold the edit link for a second or so, everything works fine. When I do a short click, it doesn't. So I tried wrapping the ajax in setTimeout(), but that didn't help. Any other ideas?
Try to use location.href in place of document.location,
jQuery.ajax({
url: location.href,
data: {
id: id
},
success: function (data) {
var newDoc = document.open("text/html", "replace");
newDoc.write(data);
newDoc.close();
},
error: function () {
alert('error');
}
});
location is a structured object, with properties corresponding to the parts of the URL. location.href is the whole URL in a single string.
Got it!
The problem is the way Firefox handles the mousedown event. It seems to abort the ajax call as soon as you relase the mouse button. I changed the event to click and everything is fine now.
jQuery('a.edit').on('click', function () {
var id = jQuery(this).attr('data-title');
jQuery.ajax({
url: document.location,
data: {
id: id
},
success: function (data) {
var newDoc = document.open("text/html", "replace");
newDoc.write(data);
newDoc.close();
}
});
});

PHP / JQuery / AJAX for Updating Database if Div is not visible

I have a complex website setup so I'll just make an example a simple one.
Current Setup
I have two buttons.
<a id="one" href="#">Link 1</a>
<a id="two" href="#">Link 2</a>
And I have two divs
<div id="showOne" style="display:none">1</div>
<div id="showTwo" style="display:none">2</div>
This is my JQuery code
$('#one').click(function (e) {
$('#showOne').show();
});
$('#two').click(function (e) {
$('#showTwo').show();
});
What I'm Trying to Accomplish
Basically, I have a database table setup that has a row to count how many times was div(showOne) and div(showTwo) shown.
How would I work with AJAX to add one to the database row aka counter if display = block?
My Attempt
$('#one').is(":visible")
{
$.ajax({
type:"POST"
url: update.php
data: {type:link_one_shown}
success: function(data){
alert("Test");
}
})
When I do this, the rest of my JQuery code crashes. Not sure if this doesn't make sense or I just wrote something wrong.
Thank you in advance!
Three problems that I can see:
As Akam notes, you've mangled the if statement.
The data isn't correct -- link_one_shown should be either a variable (which you haven't defined?) or a string literal.
You're missing commas between the ajax function parameters.
Here's the modified code:
if ($('#showOne').is(":visible")) {
$.ajax({
type:"POST",
url: update.php,
data: { type: "link_one_shown" },
success: function(data){
alert("Test");
}
});
}
why not just move ajax call to function and invoke it when show the div, this avoids code repetition and makes it simpler.
$('#one').click(function (e) {
$('#showOne').show();
updateDB('link_one');
});
$('#two').click(function (e) {
$('#showTwo').show();
updateDB('link_two');
});
function updateDB(link)
{
$.ajax({
type:"POST"
url: update.php
data: {type:link}
success: function(data){
alert("Test");
}
});
}

Performing update query then change page in Jquery Mobile

I have a confirmation dialog that leads to an update query when the user clicks a link.
<div class="ui-bar">
<a id="confirm" href="#" data-strid="<?php echo $str_info['str_id'] ?>">Confirm</a>
</div>
What I am looking to do is run an update query, then reload the previous page with the updated information on it.
I thought I accomplished this, but some sort of error keeps popping up in firebug and the ajax doesnt seem to be successful. The error only comes when I reload the page...and when I put a delay on it, there is no error, so I can't even read what it is.
<script>
$('#confirm').click(function (){
var str_id = $("#confirm").data("strid");
$.ajax({
type: "POST",
async: true,
url: '../../ajax/add_land',
dataType: 'json',
data: { str_id: str_id },
success: function(){
}
});
$('.ui-dialog').dialog('close')
setTimeout(
function()
{
location.reload()
}, 750);
return false;
});
</script>
Is there any good way of accomplishing this? Again, in summary, I am looking to perform an update query, then reload the last viewed page (not the dialog) so that the changed info is displayed. ../../ajax/add_land is in PHP.
There are few better ways of achieving this but that is beyond the point, in your case you should do this:
<script>
$('#confirm').click(function (){
var str_id = $("#confirm").data("strid");
$.ajax({
type: "POST",
async: true,
url: '../../ajax/add_land',
dataType: 'json',
data: { str_id: str_id },
success: function(){
$('.ui-dialog').dialog('close');
location.reload();
}
});
return false;
});
</script>
When ajax call is successfully executed it will call code inside a success callback. Ajax call is asynchronous action, that means rest of the code is not going to wait for it to finish. Because of this success callback is used. So there's need for the timeout.
One more thing, there's also an error callback, use it to debug ajax problems:
error: function (request,error) {
alert('Network error has occurred please try again!');
},

Issue with using a value in JQuery/Javascript

I have a PHP populated table from Mysql and I am using JQuery to listen if a button is clicked and if clicked it will grab notes on the associated name that they clicked. It all works wonderful, there is just one problem. Sometimes when you click it and the dialog(JQuery UI) window opens, there in the text area there is nothing. If you are to click it again it will pop back up. So it seems sometimes, maybe the value is getting thrown out? I am not to sure and could use a hand.
Code:
$(document).ready(function () {
$(".NotesAccessor").click(function () {
notes_name = $(this).parent().parent().find(".user_table");
run();
});
});
function run(){
var url = '/pcg/popups/grabnotes.php';
showUrlInDialog(url);
sendUserfNotes();
}
function showUrlInDialog(url)
{
var tag = $("#dialog-container");
$.ajax({
url: url,
success: function(data) {
tag.html(data).dialog
({
width: '100%',
modal: true
}).dialog('open');
}
});
}
function sendUserfNotes()
{
$.ajax({
type: "POST",
dataType: "json",
url: '/pcg/popups/getNotes.php',
data:
{
'nameNotes': notes_name.text()
},
success: function(response) {
$('#notes_msg').text(response.the_notes)
}
});
}
function getNewnotes(){
new_notes = $('#notes_msg').val();
update(new_notes);
}
// if user updates notes
function update(new_notes)
{
$.ajax({
type: "POST",
//dataType: "json",
url: '/pcg/popups/updateNotes.php',
data:
{
'nameNotes': notes_name.text(),
'newNotes': new_notes
},
success: function(response) {
alert("Notes Updated.");
var i;
$("#dialog-container").effect( 'fade', 500 );
i = setInterval(function(){
$("#dialog-container").dialog( 'close' );
clearInterval(i);
}, 500);
}
});
}
/******is user closes notes ******/
function closeNotes()
{
var i;
$("#dialog-container").effect( 'fade', 500 );
i = setInterval(function(){
$("#dialog-container").dialog( 'close' );
clearInterval(i);
}, 500);
}
Let me know if you need anything else!
UPDATE:
The basic layout is
<div>
<div>
other stuff...
the table
</div>
</div>
Assuming that #notes_msg is located in #dialog-container, you would have to make sure that the actions happen in the correct order.
The best way to do that, is to wait for both ajax calls to finish and continue then. You can do that using the promises / jqXHR objects that the ajax calls return, see this section of the manual.
You code would look something like (you'd have to test it...):
function run(){
var url = '/pcg/popups/grabnotes.php';
var tag = $("#dialog-container");
var promise1 = showUrlInDialog(url);
var promise2 = sendUserfNotes();
$.when(promise1, promise2).done(function(data1, data2) {
// do something with the data returned from both functions:
// check to see what data1 and data2 contain, possibly the content is found
// in data1[2].responseText and data2[2].responseText
// stuff from first ajax call
tag.html(data1).dialog({
width: '100%',
modal: true
}).dialog('open');
// stuff from second ajax call, will not fail because we just added the correct html
$('#notes_msg').text(data2.the_notes)
});
}
The functions you are calling, should just return the result of the ajax call and do not do anything else:
function showUrlInDialog(url)
{
return $.ajax({
url: url
});
}
function sendUserfNotes()
{
return $.ajax({
type: "POST",
dataType: "json",
url: '/pcg/popups/getNotes.php',
data: {
'nameNotes': notes_name.text()
}
});
}
It's hard to tell from this, especially without the mark up, but both showUrlInDialog and sendUserfNotes are asynchronous actions. If showUrlInDialog finished after sendUserfNotes, then showUrlInDialog overwrites the contents of the dialog container with the data returned. This may or may not overwrite what sendUserfNotes put inside #notes_msg - depending on how the markup is laid out. If that is the case, then it would explains why the notes sometimes do not appear, seemingly randomly. It's a race condition.
There are several ways you can chain your ajax calls to keep sendUserOfNotes() from completing before ShowUrlInDialog(). Try using .ajaxComplete()
jQuery.ajaxComplete
Another ajax chaining technique you can use is to put the next call in the return of the first. The following snippet should get you on track:
function ShowUrlInDialog(url){
$.get(url,function(data){
tag.html(data).dialog({width: '100%',modal: true}).dialog('open');
sendUserOfNotes();
});
}
function sendUserOfNotes(){
$.post('/pcg/popups/getNotes.php',{'nameNotes': notes_name.text()},function(response){
$('#notes_msg').text(response.the_notes)
},"json");
}
James has it right. ShowUrlInDialog() sets the dialog's html and sendUserOfNotes() changes an element's content within the dialog. Everytime sendUserOfNotes() comes back first ShowUrlInDialog() wipes out the notes. The promise example by jeroen should work too.

Get only part of the message and reload only one div

this is an ajax method that inserts the data into a db and should supposedly display the new content.
<script type = "text/javascript">
$(document).ready(function() {
$('#submit').live('click', function(eve) {
eve.preventDefault() ;
var form_data = {
title: $('#title').val()
};
$.ajax({
url: "http://localhost/ci/index.php/chat/comment",
type: 'POST',
data: form_data,
success: function(msg) {
alert(msg);
}
});
});
});
</script>
However in my /chat/comment, i am loading the view again, i.e, user submits a comment, load the view again and the comment should be there. My response from server is the view's HTML. However the view comes with all the divs and there are many of them. I need to retrieve only part of the div, say, #commentspace from the ajax on success.
Look at the jQuery $.load() function?
Example
Inside "firstpage.html"
$('#content').load('secondpage.html #content');
